Abstract

The invention relates to the field of a tobacco bale, and discloses a preparation method of burning and printing the tobacco bale. The method comprises the steps of: before printing printing ink on alumite, bottoming the alumite with UV (Ultraviolet) varnish in an offset printing manner, wherein wet press is required, the bottoming thickens with varnish required is 2-4 microns; and after the bottoming step, printing the printing ink on the bottom, so that the varnish has a connection effect between the alumite and the printing ink. With the adoption of the technical scheme, common alumite, printing ink and the like can be printed on a machine, so that the universality of materials is extremely improved, and the product cost is lowered to a great extent. Operation which is previously harsh is practical, simple and effective, the production progress is greatly accelerated, the product quality is improved, and the industrial problems are effectively solved.

Description

The preparation technology of tobacco bale first ironing and then printing

Technical field

The present invention relates to the tobacco bale field, is a kind of preparation technology of tobacco bale first ironing and then printing.

Background technology

Development along with tobacco market; and in order to satisfy people to the needs of external packing vision; cigarette trademark is constantly reformed material and the outward appearance of packing and decorating; in recent years; cigarette trademark adopts various gold stamping forms mostly; but during the such product of explained hereafter routinely; cost is high; have a big risk; the problem that occurs in the process of production is also more; wherein the most outstanding is that the adhesive rate of printing ink on anodized aluminium is bad; final products produce the phenomenon that printing ink fades; and then brought Qualified Products Rate low; it also is present each printing house urgent need to solve the problem so fade; with regard to cigarette trademark; the product of printing also is will be through the friction in various degree of bag cigarette machine in cigarette factory; if printing ink on paper or anodized aluminium in conjunction with bad; will certainly cause cigarette can't pack production; and the great quality problems that the product of producing often can occur fading; the loss that causes also is quite large; although is solving with diverse ways each printing house; but can not resolve for a full due this technical barrier; and when addressing this problem; some new problems that affect quality have been brought again; finally attend to one thing and lose sight of another; put up with at two, produces reluctantly, is badly in need of solving so the adhesive rate of printing ink on anodized aluminium is each printing factory; one of technological difficulties that emphasis is captured.

Because conventional is gold stamping, ' print afterwards first and scald ' or gold stampingly do not republish other pattern above rear, because anodized aluminium is to belong to metal species, offset ink is to belong to resinae, and they itself just can be not fine in conjunction with getting, and the anodized aluminium surface brightness is high, smooth smooth, it is just relatively relatively poor that printing ink is imprinted on top adhesive rate, so when delivering to cigarette factory bag cigarette after printing is finished in the printing house, will produce the phenomenon that fades by the friction in the bag cigarette machine bag cigarette process.

Summary of the invention

The objective of the invention is to provide a kind of preparation technology of tobacco bale first ironing and then printing can thoroughly solve the problem that fades.

Technical scheme of the present invention is: before printing ink on the anodized aluminium, make a call to the end with offset printing UV varnish one at anodized aluminium, and require to do for wet pressing, the bottoming thickness requirement of varnish is at 2-4 μ m, after the bottoming operation is finished, printing ink republishes on bottoming, and varnish plays a connection function between anodized aluminium and printing ink like this.

Owing to having adopted technique scheme, the materials such as general anodized aluminium, printing ink can be printed on the machine, greatly improved the popularity with the material aspect, its product cost reduces significantly, also by the harshness in past, become practicality, simple, effective in operation, its manufacturing schedule is also accelerated greatly, improve the quality of product, effectively solved the difficult problem of industry.

The specific embodiment

The present invention is further illustrated below in conjunction with embodiment.

After gilding press is pressed suitable operation and the hot anodized aluminium of quality requirement, shine a bottoming version in offset printing with the anodized aluminium film, implement one varnish bottoming of offset printing printing, its power of lamp tube is pressed the normal power of offset press, need not change, the varnish printing ink quantity necessarily can not be too large, because varnish belongs to colourless, adding that anodized aluminium is radium-shine silver color or gold, so be difficult to judge whether to meet China ink amount size requirements, because the varnish China ink was measured conference and is brought two road printing ink not print or fade more serious, the too small effect that does not have connection of China ink amount is still faded, if there is not instrument to detect its China ink amount thickness, will be in the other supporting two road versions that fill of offset press while, repeatedly test, detect, concrete detection method is heavily to scrape the two road printing ink of having accomplished fluently the end with nail or coin, until top printed printing ink does not fall, just can determine the appropriate degree of varnish China ink amount size, in case after determining, ink fountain China ink amount and the space of a whole page moisture of bottoming equipment will strictly be controlled, and will be through nail commonly used or Detecting of coin in the process of normal printing.Through such PROCESS FOR TREATMENT, the product that prints is can not produce the phenomenon that fades again.

Claims

1. the preparation technology of tobacco bale first ironing and then printing, it is characterized in that before printing ink on the anodized aluminium, make a call to the end with offset printing UV varnish one at anodized aluminium, and require to do for wet pressing, the bottoming thickness requirement of varnish is at 2-4 μ m, after the bottoming operation was finished, printing ink republished on bottoming, and varnish plays a connection function between anodized aluminium and printing ink like this.
